Comparing: T34 vs. IS-3

Developed in 1945 as a modernization of the T30 heavy tank. The vehicle was equipped with the 120 mm T53 gun and the new Continental AV-1790 engine. Because of the decline in heavy tank development after the end of World War II, the T34 never entered service. The prototypes were used in field trials.

Mass production of the vehicle started in May 1945. On September 7,1945, IS-3 tanks took part in the Allied Victory Parade through Berlin. A total of 1170 vehicles were manufactured by the end of 1946, when production was canceled. From 1948 through the late 1950s, the tanks underwent a number of modernization refits.
